Bitbucket Server pull requests is undoubtedly a fantastic feature that helps collaboration. GitFlow integration in Sourcetree is another nice feature that helps promoting good processes in development process.
Unfortunately these two features do not work together well. Wouldn't it be nice to have the GitFlow functionality amended in case master and develop branches are protected from merges without pull requests? This would make Sourcetree to a completely new level and would make it tool of choice for a wider audience.
